Checksum:
EOR of all data bytes. First byte after data is the checksum value.
Notes:
Loader is used on side 1 of ACE, side 2 uses a different loader.
Load addresses and sizes are hardcoded. New addresses gets loaded along the way.
File 1 and 3 is divided into areas, each area starts with lead-in and sync.
All files/areas seems to have a ~2040 trailing zero bits.
These are the load addresses and end addresses:
End addreses are exclusive.
1a - 0xC000-0xC241
1b - 0x02EA-0x02FA
2 - 0x0F00-0x2000
3a - 0x0810-0x4000
3b - 0x41B8-0xD000
3c - 0xE000-0xF800
3d - 0xFC00-0xFFFF
